WILLIAM B. PAGE, DIXON, ILLINOIS.

SPECIFICATION forming part of Letters Patent No. 754,494, dated March 15, 1904. Application filed January 21, I901. Serial No. 44,192- (No model.)

To all whom it may concern:

Be it known that I, WILLIAM B; PAGE, a citi- Zen of the United States,-and a resident of Dixon, in the county of Lee and State of Illinois, have invented certain new and useful Improvements in Machines for Washing Vessels or Receptacles; and I do hereby declare that the following is a full, clear, and exact description and more particularly that class of washingmachines designed to wash milk-cans or other cylindric or partlycylindric receptacles. Heretofore in inventions of this class revolving brushes have been used which were inserted into the receptacles and revolved therein. This, however, has not been satisfactory, inasmuch as it has been diflicult for all parts of the can to be reached by the brush, and it is a matter of common experience that if any part of the interior of the can remains unclean it has the effect of tainting the contents, and not only thereby injuring the quality of its contents, but as well seriously endangering the health of the users.

The object of my invention is to obviate the possibility of any part of the can or receptacle remaining unclean.

The invention provides means'not only for i washing, but also for sterilizing or partly sterilizing the vessel during the washing operation.

The invention consists of the matters hereinafter described, and more fully pointed out' and defined in the appended claims.

In the drawings, Figure 1 is a top plan view of a device embodying my invention. Fig. 2 is a'verticalsection of the same. Fig. 3 is a section taken on line 3 3 ofFig. 2. Figs. 4, 5, and 6 are details of parts of my invention. Fig. 7 is a modified form of the brush.

As shown in the drawings, A indicates a .receptacle or tank of any desired form or construction. 4 B indicates a oold-water-inlet pipe; B, a steam-pipe provided at its lower end near the bottom of the tank with an apertured pipe 6, through which steam may be admitted to liquid contained insaid tank, with the efiect of raising the temperature of said liquid.

B B are overflow-pipes, the open ends of which extend upwardly in the tank to'a point lower than the top thereof, as indicated in Fig. 2. Said overflow-pipe connects through the bottom of the tank with the drain-pipe B which communicates with the sewer or other place of discharge for the. waste fluid. The

.cold-water-inlet pipe B and the steam-pipe B are each provided with a valve 6 I2 respectively, whereby the inflow of cold water or steam may be under the control of the operator at all times.

C indicates a vertically-movable standard and 2, and is provided with a brushremovably secured thereon by any well known means and adapted to extend within the receptacle to be washed when in operation. Said standard C is slidably'mounted on one end of said tank, as indicated in Figs. 1 and 5, by means of a plurality of cleats 0 0, arranged oppositely and which engage the flanges 0' c on each side of the standard. Means are provided for adjusting said standard and brush-arm vertically, comprising a hand-wheel D, secured on a screw threaded shaft d, which passes through an apertured block (2, rigidly secured on the front end of the tank. Said shaft has screw-threaded engagement with said standard C, and the rotation thereof acts to move said standard up or down, thereby adjusting vertically the brush-arm. Said brush,;as' shown, consists of an approximately horizontal portion 0 convex laterally and conforming longitudinally downwardly-extending part of said brush 0 is integrally connected with the brush portion c and is of a greater length than the radius of a receptacle or vessel to be washed. Obviously the form of the'brush may vary with the shape of the receptacle to be washed thereby, and said brushes are removably secured-on said 'is shown as a milk-can of familiar form. A

arm C, so that the same may be removed for cleansing or repairs or for the purpose of securing a brush of other form or shape thereon when it is desired to wash receptacles of a different form.

E indicates a pipe or connection for boiling Water or superheated steam, which is connected in the brush-arm C and communicates with a passage extending tlierethrough, which opens into said tank ata point beneath the brush and within the receptacle when the same is secured in position for cleansing on said brush. 5 indicates a valve of any desired form connected in said pipe E, whereby the flow of the heated fluid thcrethrough may be controlled by the operator. Means are provided for rotating a can on said brush, comprising the shafts F F, which extend through the end of the tank on each side of said brush-standard through stufiing-boxes of any desired form to the interior of said tank. Said shafts are parallel, .as shown, and provided at their outer ends with sprocket wheels, over which is trained a sprocket-chain f, which is driven from the shaft F journaled on the said end of the tank. Said shaft is provided with tight andloose pulleys in a familiar manner. The inner ends of said shafts F. and F are journaled in bearingsf f, rigidly secured on the floor of the. tank, as shown in Figs. 1 and 2. Each of said shafts F and F are provided within the tank with friction-rollers G G G G of which the rollers G G are each secured intermediate of the bearings of said shafts and the rollers Gr G secured at the extremities of the shafts beyond the bearings f f. The rollers, as shown, are provided on their periphery with a rubber or other resilient tread-surface, which in the drawings is shown as convex transversely. I

H H indicate bracket-arms secured on a side of the tank and projecting inwardly and having journaled on the extremities thereof a bell-crank lever. 'At the extremities of the forwardly-projecting arms it h of, said bell-- crank lever is journaled a friction-roller H, similar to the rollers G and G on the shafts F and F and also provided with a resilient tread. Said roller H is adapted to be swung forwardly and downwardly to engage the periphery of the can or other vessel when supported on the brush and the rollers G and G by means of the lever Hiwhich is connected with the arm 7b of the bell-crank lever by aconnecting-rod hi which is pivotally secured at the outer end of said arm. Said connecting-rod k may-be secured to said lever H in any desired manner. As shown, however, said lever isa bent lever and is provided intermediate of its ends with an inwardly-projecting fitting pivoted thereon provided with a longitudinal screwthreaded socket, and said connecting-rod is complementally screw-threaded and engages therein. The form of said lever is such that when the friction-roller H is moved into engagement with the can or receptacle said con necting-rod and the bent end of the lever are.

and the disk H being elevated to the point.

indicated by dotted lines .in Fig. 2, a can (shown in dotted lines in Fig. 2) is inserted onthe brush and supported thereon and on the friction-rollers G G G G The frictionroller H is then turned down by means of said lever into contact with the outer surface of the can directly above the brush and acts to hold the can thereon. Boiling or hot water is then admitted into the can through the pipe E and rotation given to the can by the lower friction-disks. Inasmuch as the brush conforms to the longitudinal configuration of one side of the can, including the neck thereof, and the parts 0 of the brush extend transversely beyond the'center of the can-bottom the entire inner surface of the can,including its neck, engages the brush during the rotation of the can, and it is obvious that all parts thereof will be thoroughly cleaned. Should the water in saidvtank at any time become cooler than is desirable, the same may be heated by admitting steam from the pipe B and the apertured pipe Z), and in a similar manner should the water become too warm cold water may be admitted through the pipe B.

As a further improvement the brush may be constructed with the longitudinal portion and end or transverse portion in separate pieces hinged together, as shown in Fig. 7,

in which case an arm or bracket 0 is provided on the longitudinal portion so located as to stop the inward swing of said end portion when a can is placed thereon and hold the brush firmly against the bottom. A spring, herein shown as a spiral pushing-spring, is secured on the bracket-arm and the transverse end portion of the brush and acts to hold said end extended, as shown in dotted lines on Fig. 7 when the can is removed therefrom.

, Many details of construction may be varied without departing from the principle of my invention.

I claim as my invention 1. A machine for washing receptacles comprising a vertically-adjustable brush adapted to extend within the receptacle and to conform to the longitudinal contour of one side thereof and extending partly across the bottom of the 'same, means for adjusting the brush to the receptacle, means for rotating the receptacle in engagement with said brush and means for injecting heated fluid within said receptacle while rotating against the brush.
